In Synthetic Leather / Leather Auxiliaries manufacturing, stable heat transfer is essential for maintaining resin quality, coating consistency, solvent management, and batch-to-batch reliability. Production lines for synthetic resin binders, PU dispersions, and specialty auxiliaries often rely on thermally controlled reactors and downstream heating systems, while modern reaction plants are commonly designed for operation up to 300°C and -1 to +10 bar using thermal oil through external half-pipe coils for heating and internal coils for direct cooling. In synthetic leather finishing, drying and foaming stages may run around 140-170°C, and PU leather drying ovens are typically controlled below 150°C to protect film quality, surface uniformity, and adhesion. Within this wide but precision-sensitive operating window,Eurotherm 320provides a dependable -30 to 320°C service range, low kinematic viscosity of 9.8 mm²/s at 40°C, and excellent thermal stability for reactors, heat exchangers, distillation units, and synthesis systems. Its low-pressure operation helps simplify thermal-system design, while its cost-effectiveness and steady heat delivery support continuous production, reduced maintenance, and more consistent performance in resin cooking, auxiliary blending, and coated-substrate processing across demanding synthetic leather operations.
